What is the mass of 5.50 mol of pure liquid bromine ?

Answers

Answer:

m Br = 439.472 g

Explanation:

mass Br = ?

∴ mol Br = 5.50 mol

∴ molar mass Br 79.904 g/mol

mass = (mol)*(g/mol)

⇒ m Br = (5.50 mol)*(79.904 g/mol)

⇒ m Br = 439.472 g

Student performs experiments on acids and bases. Which is not a scientific experiment? She uses an acid-base indicator to measure the pH of four different solutions.

She mixes two solutions and measures their pH before and after.

She asks her lab partner which base he thinks is hardest to study. <-- my answer

She measures the temperature of a solution before and after adding H2SO4.

Answers

Answer: Option (c) is the correct answer.

Explanation:

An experiment conducted by following a detailed and organized series of steps in such a manner that its result will reject or validate the hypothesis.

For example, using an acid-base indicator will help to measure the pH of a solution.

A scientific reaction is performed in controlled conditions with proper precautions unless it could be dangerous to perform the experiment.

Therefore, we can conclude that she asks her lab partner which base he thinks is hardest to study is not a scientific experiment.

she ask her lab partner which base he thinks is hardest to study
you are correct because that not an experiment its a question

What is volume? What instrument is used to measure liquid volume? What formula is used to calculate the volume of a solid object.

Answers

We are required to explain the meaning of volume and mention the instrument used to measure liquid volume.

Volume refers to the unit of three-dimensional measure of space that comprises of a length, a width and a height. It is measured in units of cubic centimeters(cm³), cubic inches(in³) or cubic feet(ft³).

An instrument used to measure liquid volume is called a graduated cylinder or a buret.

Since, volume comprises of length, width and height, then the formula used to calculate the volume of a solid object is length multiplied by width multiplied by height.

Therefore,

Volume of a solid object = Length × Width × Height

Answer:

Volume is the amount of space that a substance occupies. A graduated cylinder is used to measure liquid volume. The formula used to calculate the volume of a solid object is = L x W x H
